| Popis: | Because FSH and its receptor play a fundamental role in reproduction, the objective of this research was determining the effect of the A-320T polymorphism in productive and reproductive traits in Antioquia Holstein cows. The PCR-RFLP was used to amplify a segment of 970 bp of the bovine follicle stimulating hormone receptor gene (FSHR) which was digested with the restriction enzyme TaqI. The effect of the FSHR genotypes on productive and reproductive traits was determinate by a Mixed Linear Model and Tukey Test was used to establish significant differences between means for the three genotypes. The effect of allelic substitution was studied through a linear regression model where the genotypes AA, AT and TT were transformed into a quantitative scale of 0, 1 and 2, respectively according to the number of possessed T alleles. In Antioquia Holstein cattle the most common genotype was the AT (0.485) followed by TT (0.417) and AA (0.096) genotypes. Allele frequencies were 0.339 for A and 0.660 for T, respectively. The FSHR genotypes did not exert a significant effect on the principal productive parameters, except for fat percentage (P |
